Abstract

A bicycle (11) with a drive mechanism (27) using reciprocal rectilinear pedal motion to propel a pinion gear (25) against a crown gear face (23) associated with a rear bicycle wheel (15), rotating the rear wheel (15). The pinion gear (25) receives motion from a helical member (37) surrounded by a slider (43). Each pedal (33) is united with the slider (43) which moves linearly along a guide or track, forcing rotation of the helical member (37) as the slider (43) is pushed rearwardly by a pedal (33). A freewheel or overrunning clutch (45) permits power transfer only when the pedal (33) moves rearwardly and allows freewheeling when the pedal (33) is reset.
